SANDING ATTACHMENT FOR AUTOMOBILES.

Application filed August 28, 1922.

To all whom it may concern:

Be it known that we, EDWARD R. TnnciiY and JOHN Nnnsoiv, citizens of theUnited States, residing at Minneapolis, in the county of Hennepin andState of Minnesota, have invented certain new and useful Improvements inSanding Attachments for Automobiles, of which the following is aspecification.

Our invention relates to sanding attachments for automobiles, and anobject is to provide a device by means of which the driver of the carcan quickly deposit sand in front of the driving wheels when the carstarts to skid on slippery surfaces, thereby checking the skiddingaction.

The full objects and advantages of our invention will appear inconnection with the detailed description, and the novel features of ourinventive idea will be pointed out in the claims.

In the accompanying drawings which illustrate the application of ourinvention in one form in which it may be embodied, Fig.

1 is a side elevation partly broken away showing the device applied toan automobile. Fig. 2 is a view in vertical section on the line 22 ofFig. 1. Fig. 3 is a view in vertical section on the line 33 of Fig.

4. Fig. 4 is a view in vertical section on the line 4-4 of Fig. 8. Fig.5 is a view in vertical section on the line 5-5 of Fig. 3.

'In the drawings, our device is shown applied to an automobile havingthe customary floor 10, dash 12, instrument board 14, and running boards15. A casing 16 which constitutes a sand box is secured to the undersideof the floor 10 by brackets 18. This casing has a neck 20 extendingthrough the floor 10 by means of which the casing may be filled withsand, the neck being provided with a closure 22 which when in place isflush with the upper surface of the floor as shown in Fig. 1. Secured byscrews 24 to the two running boards 15 on opposite sides of the car aresand receptacles 26 into which extend pipes 28 leading downwardly fromthe opposite ends of the casing 16. The two receptacles 26 are alike andhence a detailed description of one of them will suffice. As shown inFig. 3, the rear wall of the receptacle 26 stops short of the bottomthereof so as to provide a discharge slot 30. This rear wall inconjunction with a partition 32 depending from the top of the re Serialno. 584,769.

ceptacle 26 forms a valve chamber, it being noted that the partition 32stops short of the bottom so as to provide a passageway 34. A rotaryvalve 36 is mounted in the valve chamber, this valve being cut away onone side to form a flat portion 38. Whcn the valve is in the positionshown in Fig. 3, it is closed, and when'rotated in the direction of thearrow so to bring the flat portion downwardly, sand will be permitted toflow out of the discharge slot 30. The two valves are secured by setscrews 40 to a rod 42 rotatably mounted in hearings in the side walls ofthe two receptacles 26. Secured to the rod 42 is a sprocket wheel 44over which passes a section of sprocket chain 46 the ends of which aresecured to crossed cables 48 and 50 which after passing around pairs ofguide sheaves 52, 54, and 56 are secured to a hand lever 58 which issupported in suitable manner as by pivoting it to the in strument board14.

The operation and advantages of our invention will be obviousinconnection with the foregoing description. When the automobile starts toskid on slippery surfaces, the driver may almost instantaneously depositsand in front of the driving wheels by pulling back on the hand lever58. A pull on this lever causes the two valves 36 to to tate in thedirection of the arrow and open the valves so that sand will flow uponthe roadway in front of the driving wheels as indicated in Fig. 1thereby quickly stopping the skidding movement. 'llhereupon the drivermay push the hand lever forwardly in order to check the flow of sand. Itwill be understood that to get the best results, the sand should be dryand of substanti ally uniform size.

We claim:

1. A sanding attachment for automobiles comprising a container for sand,receptacles positioned in front of the driving wheels, pipes leadingdownwardly from said container to the forward portion ofsaidreceptacles, said receptacles each having a chamber formed by the rearwall thereof and a partition therein, said wall and partition stoppingshort of the bottom of the receptacle to form discharge slots, a rotarycylindrical valve in said chamber said valve being flat on one side, andoperating means within reach of the driver whereby said valves may bepartially rotated to bring their flat portion either adjacent the bottomof said receptacles or adjacent said partitions. I

2. A sanding attachment for automobiles comprising a container for sand,shutofi' devices connected with said container and positioned in frontof the driving wheels, a

rotatable rod to which said shutofi devices are secured, a sprocketwheel secured to said rod, a section of sprocket-chain passing aroundsaid sprocket wheel, cables secured to the ends of said sprocket-chain,and operating means within reach of the driver to which said cables areattached.
